Definitions

  • the present invention relates to a cable connector assembly, and more particularly to a cable connector assembly with an improved cable for high speed signal transmission.
  • USB Universal Serial Bus
  • USB-IF USB-IF was founded to define a spec of USB.
  • USB-IF has published several editions for USB, and transmission rate of USB has become higher and higher.
  • higher transmitting rate of USB based connection accessory is needed.
  • U.S. Pat. No. 8,100,725 issued to Su et al. on Jan. 24, 2012, discloses a cable connector assembly in accordance with USB 3.0 standard.
  • the cable connector assembly comprises five first contacts for transmitting high speed signal and four second contacts compatible to the version USB 2.0 standard, and the first contacts are connected with two pairs of differential wires.
  • signal transmitting rate of the cable connector assembly reaches to 10 Gbps or the transmitting distance becomes farther, a passive equalizer cable or an active cable capable of amplifying signal is needed to connect with the first contacts, thus high cost will be incurred for manufacturing the cable connector assembly.
  • an improved cable connector assembly with an equalizer function for increasing transmitting rate and distance is desired to overcome the above problems.
  • a cable connector assembly comprises an insulative housing defining a cavity, a plurality of contacts retained in the insulative housing, a metallic shell enclosing the insulative housing, and a cable electrically connected with the contacts.
  • the contacts comprises a number of first and second contacts

  • a cable used for a cable connector assembly comprises two pairs of differential wires, each pair of differential wires comprises a pair of signal wires for transmitting high-speed signal, a grounding wire and an insulative outer jacket wrapped on the signal wires and the grounding wire, each signal wire includes a plurality of inner wires and an insulator enclosing on the inner wires, a metallic conductive layer is defined between the inner wires and the insulator.
  • FIG. 1 is an assembled, perspective view of a cable connector assembly according to the present invention
  • FIG. 2 is an exploded view of the cable connector assembly shown in FIG. 1 , with a plastic case removed away;
  • FIG. 3 is similar to FIG. 2 , but viewed from another aspect
  • FIG. 4 is an assembled, perspective view of a pair of differential wires of the cable connector assembly shown in FIG. 2 ;
  • FIG. 5 is an exploded view of the pair of differential wires shown in FIG. 4 ;
  • FIG. 6 is a front elevation view of the pair of differential wires shown in FIG. 4 .
  • the cable connector assembly 100 is a B-type USB 3.0 plug.
  • the cable connector assembly 100 comprises an insulative housing 1 , a plurality of first and second contacts 2 , 3 retained in the insulative housing 1 , a spacer 4 assembled to the insulative housing 1 for retaining the first and second contacts 2 , 3 , a cable 5 electrically connected with the first and second contacts 2 , 3 , a metal shell 6 enclosing the insulative housing 1 for EMI protection, and a plastic case 7 surrounding the metal shell 6 .
  • the insulative housing 1 is molded of dielectric material such as plastic or the like, and comprises a main portion 11 and a pair of latch arms 12 extending backwards from lateral sides of the main portion 11 .
  • Five passages 112 are defined on a top surface of the main portion 11 , and the main portion 11 has a projecting portion 113 on a back section thereof, the projecting portion 113 is extruding upwards from the top surface of the main portion 11 .
  • the projecting portion 113 has five channels 114 communicated with corresponding passages 112 .
  • the main portion 11 defines a cavity 115 recessed backwards from a front surface thereof, and a plurality of slots 116 are arranged on an upper wall and a lower wall of the cavity 115 .
  • the first contacts 2 are retained in the passages 112 and include a first pair of differential contacts for transmitting high speed signal, a second pair of differential contacts for receiving high speed signal, and a grounding contact located between the first and second pairs of differential contacts.
  • Each first contact 2 has a tail portion, and five tail portions of the first contacts 2 are arranged on a first level.
  • the second contacts 3 are retained in the corresponding slots 116 and adapted for B type USB 2.0 protocol, tail portions of the second contacts 3 are located on a second level.
  • the spacer 4 is assembled to a back end of the insulative housing 1 , and has a pair of tabs (not labeled) on both sides thereof to engage with corresponding latch arms 12 .
  • a plurality of grooves 41 are defined on a back segment of the spacer 4 for retaining tail portions of the contact.
  • the cable 5 comprises two pairs of differential wires 51 mechanically and electrically connected with the first contacts 2 , and a plurality of individual wires 52 electrically connected with the second contacts 3 .
  • each pair of differential wires 51 comprises a pair of signal wires 511 for transferring high-speed signals, a grounding wire 512 and an insulative outer jacket 513 wrapped on the signal wires 511 and the grounding wire 512 .
